钨源与浸渍方法对 MCM-41负载的NiW 基加氢脱氮催化剂的影响
Effects of W precursor and impregnation method on hydrodenitrogenation over NiW based catalysts
摘要
Abstract
The effects of W precursors (phosphotungstic acid (HPW), ammonium paratungstate (APT)) and impregnation methods (co-impregnation (CI), sequential impregnation (SI)) on the structure and quinoline hydrodenitrogenation behavior of MCM-41 supported NiW catalysts were investigated. The catalysts were characterized by XRD, FT-IR, DRS, XPS and Py-IR techniques. The results showed that the catalyst with APT as W precursor prepared by co-impregnation exhibited the highest HDN activity. This catalyst exhibited the highest dispersion of W species and the highest amounts of active species and acidic sites.关键词
